Choosing best quality a-Al2O3 powder and high purity burn magnesia powder as raw material ,
sintered after 2200celsius degree in electric arc furnace.
Fused magnesia-alumina spinel have following features:
1.big bulk density
2.Good thermal shock resistant
3.Good anti-erosion property
Main application:
a.For high quality refractory castable
b.As material for slide gate and lining brick of ladle etc.
